Answer 1

Answer:

Endocrine disruptors are the synthetic or natural chemicals that may interfere with the functioning of the endocrine system in the human body. These chemicals mimic the naturally occurring hormones produced in the body like estrogen (a female sex hormone) and androgen (a male sex hormone) also these interfere with the production of the thyroid hormone. They bind to the receptors present in a cell and prevents the endogenous hormone from binding. The normal signaling process fails to respond properly.

Trace the path of an egg cell by filling in the blanks. After the egg breaks through the ovarian wall, it travels into the _____, which overlies each ovary. From there, it reaches the _____, or womb. If the egg is fertilized by a sperm cell, it is implanted in the _____. uterus; ovary; fallopian tube ovary; fallopian tube; uterus fallopian tube; uterus; endometrium endometrium; uterus; fallopian tube

Answers

The sequence of the answers is Fallopian tube, uterus and endometrium. The egg cell travels into the Fallopian tube which the ovaries are found. Then, it reaches the uterus. If fertilization happened it will be implanted into the endometrium.

Final answer:

The path of an egg cell after ovulation is from the ovary to the fallopian tube, then to the uterus, and if fertilized, it implants in the endometrium.

Explanation:

After an egg cell is released from the ovarian wall during ovulation, it first moves into the fallopian tube that sits adjacent to each ovary. The egg cell then travels down the fallopian tube towards the uterus - also known as the womb. If the egg gets fertilized by a sperm cell during its journey, it will implant itself in the endometrium, which is the inner lining of the uterus and supports the growing embryo in early pregnancy. Hence, the correct fill-in the blanks for this question is: fallopian tube; uterus; endometrium.
